Folklore has it that "where mistletoe stays in the house, love stays also." Its association with love and fertility go all the way back to Druidic times, and survives today as the Christmas kiss under the mistletoe. As a medicinal herb, mistletoe is extraordinarily potent. It is being investigated for anti-cancer, immuno-modulating properties. It has traditionally been used as a treatment for high and low blood pressure, and for epilepsy.
